chinois. 为了解国内现有小麦品种的抗条锈性及品质状况，对40个小麦品种（系）的品质参数,以及反映小麦条锈病发生程度的量化指标进行了测定，分析了小麦品质与抗条锈性的相关关系，同时筛选了影响小麦品种抗条锈性的主要品质参数。结果表明：（1）形成时间、稳定时间、评价值与小麦条锈病普遍率间存在正相关性，相关系数达到显著或极显著水平；（2）品质性状中稳定时间是影响小麦条锈病的最主要自变量，加强小麦品种稳定时间的选择在一定程度上可降低小麦品种(系)的抗条锈性水平。

Quality characters, measure standards to reflect the serious degree of stripe rust and the correlation of them were studied through 40 common wheat, meanwhile the main quality characters to affect the resistance to disease were selected. The results were as follows: (1) Disease incidence was positively correlative with development time, stability time and evaluation value, and the correlative coefficient reached 1% or 5% level. (2) The stability time of quality characters was the most important development variable in determining disease incidence, therefore strengthening the selection of stability time, to some degree, would probably decrease the resistance to stripe rust.
